p r a UNITED STATES PATENT QFFIQEQ XVILLIAM E. lVILD, OF CANDALARA, NEVADA.

GRAIN CLEANER, SEPARATOR, AND GRADER.

SPECIFICATION forming part of Letters Patent No. 275,105, dated April 3, 1883,

Application filed October 20, 1882. (No model.)

To all whom it may concern Be it known that Ll/VILLIAMEDWARD WILD, of Oandalarafln the county of Esmeralda and State of Nevada, have invented. a new and useful Improvement in Grain Cleaners, Separators, and Graders, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 is a sectional side elevation of my improvement. Fig. 2 is a plan view of the same, partly in section through the line as m, Fig. 1.

The object of this invention is to facilitate the cleaning, separating, and grading of grain.

A represents the frame of the machine, within which are placed two shoes, B 0, arranged one above the other and in reversed positions.

To the sides of the shoes B O are attached gudgeons D, two or more to each shoe, and which slide in grooves, slots, or other ways, E, formed in or attached to the frame A.

To the frame A, midway between the shoes B U, is pivoted the center of a three-armed lever, F, the ends of the upper and lower'arms of which are pivoted to the sides of the said shoes B C. To the end of the horizontal arm of the lever F is pivoted the upper end of conmeeting-bar G, the lower end of which is pivoted to crank-wheel or crank H, formed upon or attached to the shaft I. The shaft Iis driven from the driving mechanism of the machine by belt and pulleys or other suitable means. Several holes are formed in the horizontal arm of the three-armedlever F, to receive the pivoting pin or bolt, so that the throw of the shoes B O can be regulated as may be required.

To the top of the frame A, above the upper end of the upper shoe, B, is attached a hopper, J, through which the grain is fed into the machine, and which is provided with a movable bottom, K, attached to the upper part of the shoe B, and so arranged that the feed will be cut off intermittingly by the vibration of the said shoe B. As the grain falls from the hopper J it is received upon the sieve L, through which the grain falls upon the apron M, placed beneath it. The coarse refuse falls from the lower edge of the sieve L, and the chaff and other light refuse are drawn by air suction into an opening of the spout N, which crosses the top of the machine, and passes down one side of the machine, and is connected at its lower end with the suction-fan connecting with a pipe, N, opening into the space over the sieve L, said fan being secured to the frame A and driven by a belt and pulleys from any convenient power. The grain that falls through the sieve L falls upon and slides down the apron M and falls upon a set of parallel bars, P, the ends of which are secured in recesses in crossbars Q, attached to the shoe B.

The bars P are quarter or three-eighth inch squareiron, and are arranged with an angle upward and at such a distance apart as will allow kernels of a desired size to pass between them, but will prevent the passage of larger kernels. The kernels that cannot pass through the spaces between the bars P slide down the said bars and pass from their lower ends upon the sieve It, which is made of sheet metal corrugated to correspond with the spaces between the bars P, and having cross-slots formed in it, as indicated in Fig. 2, the light lines indicating the corrugations and the heavy black lines the cross-slots. \Vith this construction the larger kernels of grain that cannot pass through the slots of the sieve It fall from the lower edge of the said sieve B into the spout S, through which they pass out of the ma chine. The kernels of grain that pass through the slots of the sieve B fall upon the apron T, placed beneath the said sieve, slide down the said apron, and fall from its lower edge into a spout, U, through which they pass out of the machine. The kernels of grain that pass through the spaces between thebarsNfall upon the apron V, slide down the said apron, and fall from its lower edge upon a second series of bars, P, which are provided with a slotted corrugated sieve, B, apron T, and spouts S U. The kernels of grain from the lowest apron,V of the upper shoe, B, fall upon the upper set of bars, P, of the lower shoe, 0, which shoe is provided with a series of bars, sieves, aprons, and spouts, in the same manner'as the upper shoe.

The width of the spaces between the bars P, and of the slots of its corresponding sieve of each succeeding set, is made a little narrower than that of the preceding set, so that the largest kernels that pass through each set will be taken out by the next set. The grain may thus bepassed successively through eight pairs of sieves, P R; or any desired number of pairs can be used, as the work to be (l-one may require.

If desired, three (more or less) of theupper aprons, V V, 850., can be finely perforated, to allow sand, grass-seed, and other fine impurities to escape, which may be received upon and allowed to escape from the bottom of the upper shoe, or may be received in a spout or other receiver and conducted out of the machine.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- WILLIAM EDYVARD WILD.
